AMD TrueAudio
TrueAudio is the name given to AMD's ASIC intended to serve as dedicated co-processor for the calculations of computationally expensive advanced audio signal processing, like e.g. convolution reverberation effects and 3D audio effects. TrueAudio is integrated into some of the AMD GPUs and APUs available since 2013. Overview TrueAudio is a DSP for audio based on Cadence Tensilica HiFi EP DSP with Tensilica Xtensa SP float support. AMD claimed that a few simple audio effects can use up to 14% of the CPU. Audiokinetic claimed that it is up to 10%. Independent software vendors (ISV), such as game developers, can use what is called a Wwise audio plugin to offload such computations to the TrueAudio DSPs. The on-die TrueAudio DSPs provide a better "silicon area to computing power" ratio and "power consumption to computing power" ratio for audio processing than the CPU, effectively making it an audio acceleration unit. Any additional benefits of the TrueAudio DSPs, such as "better ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Application Programming Interface
An application programming interface (API) is a way for two or more computer programs to communicate with each other. It is a type of software interface, offering a service to other pieces of software. A document or standard that describes how to build or use such a connection or interface is called an ''API specification''. A computer system that meets this standard is said to ''implement'' or ''expose'' an API. The term API may refer either to the specification or to the implementation. In contrast to a user interface, which connects a computer to a person, an application programming interface connects computers or pieces of software to each other. It is not intended to be used directly by a person (the end user) other than a computer programmer who is incorporating it into the software. An API is often made up of different parts which act as tools or services that are available to the programmer. A program or a programmer that uses one of these parts is said to ''call'' that ...

Graphics Core Next
Graphics Core Next (GCN) is the codename for a series of microarchitectures and an instruction set architecture that were developed by AMD for its GPUs as the successor to its TeraScale microarchitecture. The first product featuring GCN was launched on January 9, 2012. GCN is a reduced instruction set SIMD microarchitecture contrasting the very long instruction word SIMD architecture of TeraScale. GCN requires considerably more transistors than TeraScale, but offers advantages for general-purpose GPU (GPGPU) computation due to a simpler compiler. GCN graphics chips were fabricated with CMOS at 28 nm, and with FinFET at 14 nm (by Samsung Electronics and GlobalFoundries) and 7 nm (by TSMC), available on selected models in AMD's Radeon HD 7000, HD 8000, 200, 300, 400, 500 and Vega series of graphics cards, including the separately released Radeon VII. GCN was also used in the graphics portion of Accelerated Processing Units (APUs), such as those in the PlayStation 4 and Xb ...

Ray-casting
Ray casting is the methodological basis for 3D CAD/CAM solid modeling and image rendering. It is essentially the same as ray tracing for computer graphics where virtual light rays are "cast" or "traced" on their path from the focal point of a camera through each pixel in the camera sensor to determine what is visible along the ray in the 3D scene. The term "Ray Casting" was introduced by Scott Roth while at the General Motors Research Labs from 1978–1980. His paper, "Ray Casting for Modeling Solids", describes modeled solid objects by combining primitive solids, such as blocks and cylinders, using the set operators union (+), intersection (&), and difference (-). The general idea of using these binary operators for solid modeling is largely due to Voelcker and Requicha's geometric modelling group at the University of Rochester. See Solid modeling for a broad overview of solid modeling methods. This figure on the right shows a U-Joint modeled from cylinders and blocks in a binary t ...

Open-source Software
Open-source software (OSS) is computer software that is released under a license in which the copyright holder grants users the rights to use, study, change, and distribute the software and its source code to anyone and for any purpose. Open-source software may be developed in a collaborative public manner. Open-source software is a prominent example of open collaboration, meaning any capable user is able to participate online in development, making the number of possible contributors indefinite. The ability to examine the code facilitates public trust in the software. Open-source software development can bring in diverse perspectives beyond those of a single company. A 2008 report by the Standish Group stated that adoption of open-source software models has resulted in savings of about $60 billion per year for consumers. Open source code can be used for studying and allows capable end users to adapt software to their personal needs in a similar way user scripts an ...

For iOS applications (apps) the iOS SDK is required. For Universal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GPGPU
General-purpose computing on graphics processing units (GPGPU, or less often GPGP) is the use of a graphics processing unit (GPU), which typically handles computation only for computer graphics, to perform computation in applications traditionally handled by the central processing unit (CPU). The use of multiple video cards in one computer, or large numbers of graphics chips, further parallelizes the already parallel nature of graphics processing. Essentially, a GPGPU pipeline is a kind of parallel processing between one or more GPUs and CPUs that analyzes data as if it were in image or other graphic form. While GPUs operate at lower frequencies, they typically have many times the number of cores. Thus, GPUs can process far more pictures and graphical data per second than a traditional CPU. Migrating data into graphical form and then using the GPU to scan and analyze it can create a large speedup. GPGPU pipelines were developed at the beginning of the 21st century for graphic ...

Radeon RX 400 Series
The Radeon 400 series is a series of graphics processors developed by AMD. These cards were the first to feature the Polaris GPUs, using the new 14 nm FinFET manufacturing process, developed by Samsung Electronics and licensed to GlobalFoundries. The Polaris family initially included two new chips in the Graphics Core Next (GCN) family (Polaris 10 and Polaris 11). Polaris implements the 4th generation of the Graphics Core Next instruction set, and shares commonalities with the previous GCN microarchitectures. Naming The RX prefix is used for cards that offer over 1.5 teraflops of performance and 80 GB/s of memory throughput (with memory compression), and achieve at least 60 FPS at 1080p in popular games such as ''Dota 2'' and ''League of Legends''. Otherwise, it will be omitted. Like previous generations, the first numeral in the number refers to the generation (4 in this case) and the second numeral in the number refers to the tier of the card, of which there are six.
